Abstract (en)

[origin: WO2006079226A1] Disclosed is a method for operating a converter circuit comprising a converter unit (1) with a plurality of triggerable power semiconductor switches and an LCL filter (3) that is connected to each phase terminal (2) of the converter unit (1). According to the inventive method, the triggerable semiconductor switches are triggered using a triggering signal (s) which is formed from reference voltages (u*<SUB>1</SUB>, u*<SUB>2</SUB>, u*<SUB>3</SUB>). Said reference voltages (u*<SUB>1</SUB>, u*<SUB>2</SUB>, u*<SUB>3</SUB>) are formed by subtracting damping voltages (u<SUB>d1</SUB>, U<SUB>d2</SUB>, u<SUB>d3</SUB>) from phase terminal reference voltages (u<SUP>*</SUP>
